the speed is slow; in the field operation, the propulsion pressure is low but the speed is
fast.
When the on-site operation of the main jacking cylinder is reversed, if the speed is too
high, the pressure will exceed the low pressure and high speed setting, and the low
pressure pump will stop the pumping, and the speed will be slower.

When the hydraulic pressure in the machine is greater than this set value, stop the hydraulic
action.
Correct pressure warning value: warn when correction pressure exceeds this setting.
